Mercedes just drove an ev from Stuggart in Germany to Silverstone F1 circuit in U.K. 700 miles without charging. Very low drag and very complex parts 3d printed to get the weight down.

Yes, that's still a prototype since it isn't mass produced as is. There are also specialized vehicles that can reach the 1000 miles but, again, nothing mass produced for the general public
At this time most EVs manage 350 or so with a few closer to 500 miles, which is half of what was stated above. I don't event think EV manufacturers are looking to reach 1000 miles, preferring instead to focus on cutting down recharge time to 80% in 5 or so minutes.
